IMPROVED FIRE-EXTINGUISHER.

Specification forming part of Letters Patent No. 99,270., dated January 25, 1870.

To all whom it may concern 'r Be it known that I, C. G. WHEELER, of Chicago, in the county of Cook and State of Illinois', have invented certain new and useful Improvements in Fire-Extinguishers; and I do hereby declare that the following isi a full, clear, and exact description thereof, reference ing part of this specication, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists ot' certain` improvements in tire-extinguishers, whereby the acid is sure to be discharged, whichever way the wheel may be turned, as hereinafter explained.

In Ithe drawings, Figure 1 represents the apparatus detached from the reservoir, and Fig. 2 is a similar View, with the parts viewed at a right angle to the position shown in Fig. 1.

As is usual, in this class of machines, I use a cover, A, which screws securely into the top of the reservoir, (not shown,) and from the cover suspend a stirrup or metal loop, B, to sustain the bottle E, which is to contain the acid. The `bottle E rests on the foot ot' the stirrup B, as represented in Figs. 1 and 2, directly under the center of the cover A, so that the rubber stopper O, which., as shown, is attached to the lower end ot' a rod, C, which screws through the cover A, will enter the mouth of the bottle when the rod C is screwed B is set a little to 011e side ot' the center, so that the bottle E, when set thereon, will rest on one edge ofthe bottom, and thus constantly tend to tip over, as represented in dotted lines, and drop -or fall ofi', as soon as the stopper O is removed, by screwing up the rod. There is a collar, Z, attached to the stirrup B, at the proper height for the neck of the bottle to rest in, this collar being open on one side to permit the bottle to tip or fall over, as represented. There is also a guard or strap,J

h, secured to the stirrup B, on the back side,

near the bottom, to prevent the bottle from being shoved too far through, and thus keep it in position.

These parts maybe varied in details, the requisites being that the bottle shall be.held directly under the screw-rod, and be so suspended that it will fall or tip over whenever the rod isv screwed up and the stopper removed.

With the apparatus thus constructed it will be seen that whenever the rod C is screwed either up or down the acid will be discharged.

If the hand-wheel D be turned so as to screw the rod C down, the conical stopper O will be forced into' the mouth ofthe bottle, thereby breaking the bottle, as represented in Fig. l, or, if turned in the opposite direction, then the bottle will fall over, in either case discharging its contents.

By this means I prevent the possibility of any delay in consequence of servants or others not knowing which way to turn the screw, which is very likely to be the case in the hurry and excitement of a tire.

I am aware that it is not new tocrush the bottle containing the acid by means of a screw; also that it is not new to withdraw the cork by a screw, and thus let the bottle turn over, and therefore I do not claim either of these plans, broadly; but having thus described my improved device, and its mode of operation,

What I claim is- The combination of the two methods of crushing and upsetting, by means of the improved device, consisting ofthe stirrup B and the screw-rod C, constructed and arranged substantially as described, so that the acid shall be certain to be discharged, whether the screw be turned in the one or the other direction, as set forth.

C. G. WHEELER.
